02Automotive industry and transportation industry Family cars alone account for approximately 10% of global carbon dioxide (CO2) emissions. So switching to zero-emission vehicles is the only option, but electric vehicles are no longer the obvious choice, and hydrogen-fueled vehicles can accelerate the transition.
Difficulties
Manufacturing low-carbon cars has become a more difficult global issue for manufacturers to negotiate. As people travel and commute less during the coronavirus pandemic, the demand for new cars has suddenly dropped. Then, the global shortage of computer chips led to the closure of car factories, and the profits that could have been reinvested in change were wiped out.
03Electric vehicles
Most importantly, the scarcity of raw materials including cobalt and nickel used in electric vehicle (EV) batteries and rising prices mean that increasing production and meeting emission targets will be more important. difficulty. But it may accelerate the adoption of hydrogen vehicles, because the government prefers hydrogen and renewable energy to replace fossil fuels.
Electric cars already have a big lead. Most car manufacturers produce battery-powered or hybrid electric vehicles. Electric vehicles are directly connected to the national grid, achieve zero emissions while driving, and have an ever-expanding infrastructure of charging points. However, in addition to more expensive models, they do not have the longer range of hydrogen fuel cell cars, and they take a long time to charge compared to the five-minute refill time.
04 Hydrogen energy vehicles
By 2030,The price of producing renewable or "green hydrogen" is expected to be four times cheaper, and the almost unlimited supply of natural gas makes it an attractive alternative. Fuel cells and hydrogen internal combustion engines are seen as solutions for zero-carbon transportation, where batteries are too heavy or unable to be used in shipping, air travel, railways, buses, trucks, and construction vehicles.
The world supports green hydrogen energy, along with wind and solar energy, to undertake important tasks in the fields of public transportation, energy storage, freight transportation and steel production. This means changing the hydrogen plant from natural gas reforming to water electrolysis, which uses electricity and catalysts to split water into oxygen and hydrogen.
05 The layout and development of hydrogen energy in various countries in the world
Critics of hydrogen vehicles often point out the lack of available pumping infrastructure-there are only about 50 public gas stations in the United States-but it can be adjusted and used. Some gas stations and pipelines. Countries such as Japan are increasing investment in hydrogen vehicles and providing subsidies to enable domestic car travel to achieve zero emissions. China has recently made great breakthroughs in solid-state hydrogen storage technology, which will have a great potential to lead the world.
Possible problems with hydrogen-fueled vehicles
Critics of the hydrogen vehicle strategy also pointed out that if improper regulation, hydrogen internal combustion engines will produce the greenhouse gas NOx. In addition, the impact of hydrogen leakage will deplete the ozone layer, so it makes sense to design safety infrastructure first.
06 Acceptance of electric vehicles and hydrogen vehicles
In terms of acceptance, hydrogen vehicles may lag behind electric vehicles by 5 to 10 years, but as the government solves the problem of traffic emissions, hydrogen vehicles and electric vehicles are very May appear at the same time. Accelerated research has brought about technologies that make cars a viable solution, and falling prices mean that policy makers are finding hydrogen economic solutions increasingly attractive.
